Abstract: A rotary position sensing assembly for an internal combustion engine includes a mounting socket rigidly attached to a structural support of a rotating component and a position sensor slidably engaged with the socket. A slidably engageable retainer maintains the sensor within the socket at a predetermined distance from the rotating component.

Abstract: A system for controlling a flow of pressurized oil in an internal combustion engine includes a cylinder head having a first internal passage arranged to receive a supply of pressurized oil from the engine, wherein the first internal passage includes a flow restrictor; and a second internal passage connecting a section of the first internal passage upstream of the restrictor with a port formed in an external surface of the cylinder head to thereby define a pressurized oil outlet. The system further includes an oil flow control module including a pressurized oil inlet defined in a first surface thereof, and a spool valve operative to direct unrestricted oil flowing through the second passage within the cylinder head into one of a plurality of fluid lines operatively connected to the cam phaser unit, whereupon the spool valve is used to variably advance or retard engine cam timing.
